ADJUSTABLE HANDLE.

Application led January 22, 1927. Serial No. 162,695.

This invention relates to a` handle adaptable for various devices andtools whereby t-he shank'and grip sections may be yadjusted to variousangles and locked in adjusted position. Such a device maybe employed fortooth brush handles andv such an embodiment is herein described torillustrative purposes only.

f vide a device of the character described which is simple, compact andeconomical. A further object of this invention is to provide a handle ofthe character described having a locking means which can lie easilymanipulated by the iiugers oit the hand grasping the handle. A furtherobject ot this invention is to provide a handle which lends itself to aconstruction ot oinate appearance.

These objects together with other objects and correspondingaccomplishi'iients are obtained by means of the ei'nbodiinentot myinvention illustrated in the accompanying drawing, in Which:

Fig. 1 is a side elevation of a tooth brush having a handle constructedin accordance With my invention; Fig. 2 is a plan vieivv oi the brush;Fig. 3 is a section as seen upon the line 3 3 of Fig. 1 on anenlargedscale,

im fragments of the handle sections being shown; and Fig. i is a.section seen on the line i .ot Fig. 3, the shank section being` `shownin straight line position with `the grip section. p ff leferring`Witlimore j iarticularity to the drawing, 5 indicates the back ot atooth brush having bristles G. The back has a shank section 7 liormingaportion ot the handle extending theret'roin. The structure Ul justdescribed is that usual in tooth brushes. The end of the shank isrounded and formed With teeth to form a segmental toothed Wheelindicated by 8. This comprises the joint portion of the shank.

A giip section 9 ot the handle is recessed at the joint end toaccommodate the portion 8 of the shank and is secured thereto by a.pivot pin 11. Slidably mounted upon the grip section 9 is a lock bar 12.This is se-k 50 cured to the bar by means of posts 18 mount-V ed in thegrip section and extending through elongated holes 14 in the lock bar.The lock bar is provided with a recess portion atthe joint end toprovide a shield 15 overlying theA segment 8. The section 9 and lock'bar`12 together Term the complete grip for the handle. These portionscorrespond in 'shape so that when the lock bar is in position lockingtheshank, the grip end oit the handle isgsyinmetrical. There areindentations in the ends'ot the lock bar to mesh with the yteeth on thejoint end`8. `It is an object ot this invention to pro- It is obviousthat by retracting the lock bar from the joint end 8, the shank is freedand may be turned to a' selectedposition a-s shown in Fig. 3. Then byprojectingthe bar against the joint end 8, the shank will be locked inits selected position. The pressure of the fingers in grasping therhandle holds the bar in position and maintains its rigidity. f

What I claim is:

1. A handle comprising sections pivotally connectedby a hinge joint, oneof said -sections having teeth disposed about the pivotal axis, theother section being split longitudt.

nally toprovide one part slidably mounted on the other part and havingindentations corresponding to said teeth for meshing therewith. j

2. handle Vcomprising a shank section and grip section, one of .saidsectionshaving a joint end with teeth extending there from, a pivot pinconnecting said sections,

said grip section being split longitudinally to form a lock bar slidablymounted on and.

forming a part of the handle having indentations corresjionding to saidteeth so as to be movable into mesh with the latten whereby to lock thesmftons in adjusted position.

3. A handle coinjirising a shank section having a segmental toothedjoint end,` a grip end having a depression at its joint end in Which thejoint end ot the shank sec- Vtion is disposed, a pivot connecting saidsections, a lock bar corresponding in shape to said grip section,mounted on the latter so a-s tofbe longitudinally slidable, said lockbar hav-ing a shield end overlying the joint end or said shank section,and indentations corresponding to said teeth for meshing with thelatterwvhereby to lock theA sections in adjusted position. v

VIn Witness that I 4claim the foregoing I have hereunto subscribed myname this 6th day of January, 1927.
